Drain pasta. Return pasta to saucepot or place in large bowl; stir in eggplant sauce to coat. Add mozzarella and toss to combine. Divide pasta mixture between 2 ungreased 13" by 9" baking dishes and spread evenly; top each with half of bread-crumb mixture. Bake 1 casserole, uncovered, 30 minutes or until top browns and sauce bubbles. Let stand 10 minutes for easier serving. Meanwhile, prepare second casserole for freezing by cooling, uncovered, at least 30 minutes in refrigerator. Cover container tightly and freeze.
